The Search for Agroislands in the Chickpea Genome

The concentration of genes that control domestication traits in so-called “agroislands” complicates breeding. Therefore, information about where such islands are located in the genome and with what traits of domestication they are associated is of great importance for further research aimed at improving modern varieties. In the search for such information in the genomes of chickpea landraces, the BayPass program was used to assess the association of single nucleotide polymorphisms with population-specific covariates chosen as complexes of domestication syndrome traits in cultivars of the same breeding purpose. The regions of the genome with which these covariates are associated are located on chromosomes 1, 5, 6, 7, and 8. These regions are potential agroislands, as indirectly confirmed by earlier data.
